MOTOR-VEHICLE AGTUATED BY FRICTION-GEAR.

Specification of Letters Patent.

Patented Aug. 13, 1907.

Application filed March 13,1906. Serial No. 305.791.

To all whom it may concern:

Be it known that we, JosEF EDUARD LABUS, architect, and GUSTAV JULIUsSCHREIBER, manufacturer, both subjects of the Emperor of Austria, andresidents of Vienna, in the Empire of Austria, XIII, Bujatti gasse 12and Vienna VII, Halbgasse 4, respectively, have invented Improvements inMotor-Vehicles Actuated by Friction-Gear; and we do hereby declare thefollowing to be a clear, full, and exact description of the invention,such as will enable others-skilled in the art to which it appertains tomake and use the same.

This invention relates to improvements in motor vehicles actuated byfriction gear and consists in the construction and arrangement of thegear and of the motor, as well as in several improvements in differentparts of the vehicle.

Figure l of the accompanying vation of the vehicle, and Fig. 2

As will be seen, the motor 1 is arranged in the forepart of the vehiclewith its shaft parallel to the wheel axles. The motor is furnished withtwo fly-wheels 3 and 4 situated outside the casing. The fiy-wheel 3 isconstructed as a disk and serves for transmitting the power to thefriction wheel 5, which is adjustably mounted on a square shaft 7. Thefriction wheel 5 moreover is connected with a rod or sleeve 6 andretates freely in a bearing independently of the sleeve. By theimpulsion given to the friction wheel 5 from the fly-wheel 3 the shaft 7is rotated, while the sleeve 6 remains at rest. In order to enable thespeed to be varied as desired the sleeve 6 is moved longitudinally bymeans of a rack 8 formed thereon and a pinion. The pinion 9 is keyed ona shaft 10 and adjusted by a handlever 13 on the steering post which isgeared with the shaft 10 through a pinion and a toothed sector 12. Theshaft 7 engages with the differential gear 16 seated on the back-wheelaxle, through the medium of the jointed shaft 14, and thereby actuatesthe back-wheels. The fly-wheels can be subjected to brake action bymeans of brake blocks which act onthe edges thereof. The friction disk 5can be pushed out forwards by being moved over the middle point of thefly-wheel 3, whereby the vehicle is driven backwards. When the frictionwheel 5 is in the middle position the vehicle remains stationary.

The motor 1 which may have any number of cylinders as preferred may beprovided with water-cooling as well as air cooling devices. In orderthat the cooling may be powerful in the latter case, fans 17, 17 or 18are arranged on both sides as well as at the back of the motor. The fans17, 17 are driven by friction disks 19 which rest on the rims of thefly-wheels 3 and 4. The fan 18 is actuated by a fiiction wheel 20situated on the side of the fly-wheel 3 that is opposite the frictionwheel 5, the shaft of the wheel 20 transmitting the drawing is a sideelea plan.

I l l l l l i motion to the fan 18 by means of belt pulleys and belts21. The bearings of the three fans are carried on the body 2 of thecasing. The arrangement of the friction wheel 20 is of particularimportance as the wheel acts likewise as a counter-pressure wheel inrelation to the friction wheel 5, whereby the bearing for the fiy-wheelis relieved.

In order that the friction wheel 5 may always be adjusted to bear withsufficient pressure against the fly wheel 3, the motor 1 is movable onthe [-shapcd bars 23, 23 through its supporting members 22 which areformed with transverse incisions. Moreover inside the E-bars screwspindles 24 are arranged which engage in suitable screw threaded lugs inthe frame members 22 (Fig. 1), whereby the motor can be adjusted inrelation to the friction wheel 5. The motor is rotated when starting bymeans of a crank 25 and bevel wheels.

What we claim as our invention and desire to secure by Letters Patentis:

1. In a motor road vehicle actuated by friction gear, the combination ofa vertically arranged motor provided with cooling ribs and seated in thefore part of the vehicle with its shaft parallel to the wheel axles,fly-wheels on the ends of said shaft, fans operatively connected withthe flywheels, one of said fly-wheels being disk-shaped, and afriction-wheel adjustably arranged across the face of said disk-shapedflywheel, substantially as described.

2. In a motor road vehicle, a motor mounted with its shaft parallel tothe wheel axles, a flywheel on the shaft adapted to act as a frictiongear wheel, undcrframe members adapted to adjustably support the motor,frame extensions on the motor arranged to rest on the under-framemembers, adjusting screw spindles mounted in the underfranie members andarranged to engage the motor frame extensions, a cooperating frictionwheel adjustable across the face of the flywheel,. and a shaft adaptedto transmit the motion from the friction wheel to the driving axle,substantially as described.

3. In a motor road vehicle, a motor mounted with its shaft parallel tothe wheel axles,'a pair of fly-wheels on the shaft, fans geared to theperipheries of the fly-wheels, a friction wheel arranged to gear withand capable of adjustment across the face of one of the fiy-wheels, anda shaft adapted to transmit the motion from the friction wheel to thedriving axle, substantially as described.

4. In a motor road vehicle, a lnotor mounted with its shaft parallel tothe wheel axles, a fly-wheel on the shaft adapted to act as a frictiongear wheel, a cooperating friction wheel adjustable across the face ofthe fly-wheel, a shaft adapted to transmit the motion from the frictionWheel to the driving axle, a counter-pressure friction wheel arranged tobear against the face of the fiy-wheel on the opposite side to the saidfriction wheel, and a fan operatively connected with thecounter-pressure wheel, substantially as described.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
